Huh, I wasn't aware that reasoning could be toggled. I use the OpenRouter API, and just saw that this is supported both via their web UI and API. I'm used to Sonnet 3.5 and 4 without reasoning, and their performance is roughly the same IME.
I wouldn't trust comparing two different models, even from the same provider and family, since there could be many reasons for the performance to be different. Their system prompts, training data, context size, or runtime parameters could be different. Even the same model with the same prompt could have varying performance. So it's difficult to get a clear indication that the reasoning steps are the only changing variable.
But toggling it on the same model would be a more reliable way to test this, so I'll try that, thanks.
